Description

[0002] Automotive spray paint is a vital part of the automobile manufacturing and maintenance process. It not only provides the car with a beautiful appearance, but also plays a protective role. Automotive spray paint includes ordinary paint, metallic paint, pearlescent paint and special type of paint.

[0003] In the process of automobile spray paint processing, it is often necessary to mix liquid and powder, wherein the stirring time should be sufficient. Generally, it is required to stir each component for at least 15 minutes before adding another component and stirring, and so on, until all components are fully stirred and mixed. In the existing automobile spray paint mixing and stirring device, in the process of mixing the paint, different kinds of liquid are mostly introduced into the mixing box, and the powder is directly fed above the liquid, and the stirring component in the device directly stirs the liquid and powder; However, since the powder is located above the liquid, the stirring component cannot directly stir the powder at the beginning. Only after the liquid has been stirred for a period of time can the powder enter the stirring range of the stirring component to achieve mixing of the powder and the liquid. This stirring method is not convenient for quick mixing of the powder, which prolongs the stirring time of the paint. Moreover, when multiple powders need to be added, the stirring time of the paint needs to be increased by a corresponding amount of time, which seriously reduces the mixing speed of the paint, makes it inconvenient for quick mixing of the liquid and powder, and reduces work efficiency.

[0016] In summary, compared with the prior art, the embodiments of the present invention have the following beneficial effects: 1. In the present invention, the switching component is placed in different states. Correspondingly, when the switching component is in the first state, the stirring component stirs different liquid materials inside the mixing box by cooperating with the rotating drum. When the switching component is in the second state, the stirring component efficiently mixes the liquid and powder materials inside the mixing box by cooperating with the rotating drum, thereby avoiding the problem that the powder materials above the liquid materials cannot be mixed quickly, and accelerating the mixing speed of the paint. At the same time, the rotating drum turns up the paint at the bottom of the inner side of the mixing box by driving the first scraper to rotate synchronously, thereby avoiding the problem that the paint at the bottom of the inner side of the mixing box cannot be stirred well. The first scraper scrapes off the paint adhering to the inner wall of the mixing box by driving the second scraper to rotate synchronously, thereby facilitating the comprehensive and uniform mixing and stirring of the paint, avoiding the problem of color difference and unevenness of the paint, and improving the uniformity and comprehensiveness of the paint mixing. 2.

The rotating disk drives the powder thereon to rotate synchronously. The rotating disk is lifted and lowered reciprocatingly in the vertical direction by sliding with the sliding column and the guide ring groove. The rotating disk drives the powder located in different feeding areas to shake by its own shaking. The powder passes through the through hole and falls above the liquid inside the mixing box, so that the powder is fully and evenly fed, avoiding the powder being fed into a certain area inside the mixing box, and facilitating the rapid and even mixing of the powder and the liquid. 3. In the present invention, in the process of the paint passing through the first through groove, the paint will move from the side with a larger cross-sectional dimension of the first through groove to the side with a smaller cross-sectional dimension of the first through groove, thereby accelerating the speed of the paint passing through the first through groove; in the process of the paint passing through the second through groove, the paint will move from the side with a smaller cross-sectional dimension of the second through groove to the side with a larger cross-sectional dimension of the second through groove, thereby decelerating the speed of the paint passing through the second through groove. By means of the first through groove and the second through groove arranged at intervals, the paint can be accelerated and decelerated differently, thereby improving the contact efficiency of different paints, accelerating the mixing efficiency, and facilitating comprehensive and uniform mixing of the paint.

[0028] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0029] In one embodiment of the present invention, see Figure 1-Figure 2 A device for mixing and stirring automobile spray paint comprises a mixing box 1 and an upper cover 2 arranged above the mixing box 1, wherein the upper portion of the mixing box 1 is respectively provided with a first liquid inlet pipe 11 and a second liquid inlet pipe 12, the bottom of the mixing box 1 is provided with a liquid outlet pipe 13, the liquid outlet pipe 13 is provided with a solenoid valve 131, a rotating drum 3 is rotatably arranged in the mixing box 1, a stirring assembly 4 for stirring the spray paint correspondingly is arranged between the rotating drum 3 and the upper cover 2, a material dividing assembly 6 is movably arranged on the inner side of the upper cover 2, a powder feeding pipe 21 corresponding to the material dividing assembly 6 is arranged on the top of the upper cover 2, and a switching assembly 5 connected between the stirring assembly 4 and the material dividing assembly 6 is arranged on the inner side of the upper cover 2.

[0030] In this embodiment, liquid material can be introduced into the mixing box 1 through the first liquid inlet pipe 11 and the second liquid inlet pipe 12, and powder material can be introduced into the material distribution component 6 through the powder material feeding pipe 21. When the switching component 5 is in the first state, the stirring component 4 stirs the different liquid materials in the mixing box 1 by cooperating with the rotating drum 3. When the switching component 5 is in the second state, the stirring component 4 uniformly feeds the powder material by cooperating with the switching component 5 and the material distribution component 6, so that the powder material is evenly dispersed above the liquid material in the mixing box 1. The stirring component 4 The liquid and powder in the mixing box 1 are efficiently mixed in cooperation with the rotating drum 3, avoiding the disadvantage that the powder above the liquid cannot be mixed quickly, accelerating the paint mixing speed, and at the same time, the paint at the bottom of the mixing box 1 and the paint adhering to the inner wall of the mixing box 1 can be mixed, improving the uniformity and comprehensiveness of the paint mixing. After the paint is mixed, the solenoid valve 131 is opened, and the mixed paint is discharged through the liquid outlet pipe 13, which has the effects of efficient and comprehensive mixing, multiple stirring, flexible switching, uniform powder feeding, reliable structure, convenient operation, and simple and practical. The powder feeding pipe 21 is provided with a screw cap 22. The setting of the screw cap 22 can prevent external dust or debris from entering the internal space of the mixing box 1 and the upper cover 2 during the paint mixing process, thereby improving the cleanliness of the paint.

[0031] In one embodiment of the present invention, see Figure 1-Figure 4 and Figure 8 The stirring assembly 4 includes a plurality of first scrapers 41 distributed circumferentially at the bottom of the drum 3, the bottom of the first scraper 41 is movably fitted with the bottom of the mixing box 1, the end of the first scraper 41 away from the drum 3 is connected to a second scraper 42 movably fitted with the inner wall of the mixing box 1, and the end of the drum 3 close to the first scraper 41 is axially evenly distributed with a plurality of stirring groups, the stirring group includes a plurality of connecting rods 44 distributed circumferentially on the drum 3, the connecting rod 44 is configured as a Z-shaped rod, the connecting rod 44 is rotatably connected to the drum 3, and the outer end of the connecting rod 44 is connected to a stirring paddle 4 3, the other end of the connecting rod 44 passes through the drum 3 and is connected to a first bevel gear 45 movably arranged on the inner wall of the drum 3, a movable rod 46 located inside the drum 3 is rotatably arranged between the mixing box 1 and the upper cover 2, and a plurality of second bevel gears 47 meshing with the corresponding first bevel gears 45 are axially distributed on the movable rod 46, a driven gear 48 is arranged on the outer wall of one end of the drum 3 away from the first scraper 41, a driving gear 49 meshing with the driven gear 48 is movably arranged on the inner side of the upper cover 2, and the driving gear 49 is connected to a motor 410 installed on the upper cover 2.

[0032] In this embodiment, when the switching assembly 5 is in the second state, the position of the movable rod 46 is fixed and cannot be rotated, the motor 410 drives the driving gear 49 to rotate, and the driving gear 49 drives the rotating drum 3 to rotate synchronously by meshing with the driven gear 48. The rotating drum 3 drives a plurality of connecting rods 44 to rotate circumferentially around the movable rod 46, and the connecting rod 44 drives the stirring paddle 43 to rotate synchronously. At the same time, since the first bevel gear 45 connected to one end of the connecting rod 44 is meshed with the second bevel gear 47 in a fixed state, when the connecting rod 44 rotates circumferentially around the movable rod 46, the first bevel gear 45 is driven by the driven gear 48. The connecting rod 44 is driven to rotate around the axis of the first bevel gear 45 by meshing with the second bevel gear 47, thereby realizing the self-rotation of the connecting rod 44 and the circumferential rotation around the movable rod 46. The connecting rod 44 is connected to the stirring paddle 43 to drive the stirring paddle 43 to rotate synchronously around the axis of the first bevel gear 45. The stirring paddle 43 stirs the powder above the liquid into the liquid by rotating in the vertical direction, thereby realizing the rotation of the stirring paddle 43 in different directions, realizing the rapid and uniform mixing of the powder and the liquid, and avoiding the problem of the powder floating above the liquid for a long time after the material is discharged. When the switching assembly 5 is in the first state, the position of the movable rod 46 is adjusted to the active state and the movable rod 46 moves synchronously with the drum 3, the motor 410 drives the driving gear 49 to rotate, and the driving gear 49 drives the drum 3 to rotate synchronously by meshing with the driven gear 48. The drum 3 drives the movable rod 46 to rotate synchronously by cooperating with the switching assembly 5 and the movable rod 46, so that the second bevel gear 47 provided on the movable rod 46 rotates synchronously with the drum 3, and the position of the first bevel gear 45 can be relatively positioned. The drum 3 fixes the angles of the connecting rod 44 and the stirring paddle 43 by relatively fixing the position of the first bevel gear 45, so that the connecting rod 44 and the stirring paddle 43 can be rotated circumferentially around the drum 3, thereby quickly mixing different liquid materials; In addition, the drum 3 drives the first scraper 41 to rotate synchronously to turn up the paint at the bottom of the inner side of the mixing box 1, thereby avoiding the problem that the paint at the bottom of the inner side of the mixing box 1 cannot be stirred well. The first scraper 41 drives the second scraper 42 to rotate synchronously to scrape off the paint adhering to the inner wall of the mixing box 1, thereby facilitating the comprehensive and uniform mixing and stirring of the paint, thereby avoiding the problem of color difference and unevenness of the paint. Among them, the first scraper 41 and the second scraper 42 are both configured as inclined plates, and a plurality of first through grooves 431 and second through grooves 432 are spaced apart on the stirring paddle 43. The top view of the first through groove 431 is an isosceles trapezoid, and the top view of the second through groove 432 is an inverted isosceles trapezoid. In the process of the paint passing through the first through groove 431, the paint will move from the side of the first through groove 431 with a larger cross-sectional dimension to the side of the first through groove 431 with a smaller cross-sectional dimension, thereby accelerating the speed of the paint passing through the first through groove 431. In the process of the paint passing through the second through groove 432, the paint will move from the side of the second through groove 432 with a smaller cross-sectional dimension to the side of the second through groove 432 with a larger cross-sectional dimension, thereby decelerating the speed of the paint passing through the second through groove 432. By means of the first through groove 431 and the second through groove 432 arranged at intervals, the paint can be accelerated and decelerated differently, thereby improving the contact efficiency of different paints, accelerating the mixing efficiency, and facilitating comprehensive and uniform mixing of the paint.

[0033] In one embodiment of the present invention, see Figure 1-Figure 7 The switching assembly 5 includes a first inner gear ring 51 fixedly arranged on the top of the inner side of the rotating drum 3, a guide cylinder 54 fixedly installed on the top of the inner side of the upper cover 2 and arranged on the outer side of the movable rod 46, a lifting plate 56 is movably arranged inside the upper cover 2, one end of the lifting plate 56 is connected to a connecting ring 55, a sliding cylinder 53 is rotatably arranged inside the connecting ring 55 and located between the movable rod 46 and the sliding cylinder 53, the outer wall of the sliding cylinder 53 is slidably matched with the inner wall of the guide cylinder 54, and the inner wall of the sliding cylinder 53 is rotatably matched with the movable rod 46 and the sliding cylinder 53. The rod 46 is slidably matched, and the end of the slide cylinder 53 close to the rotating cylinder 3 is connected to an outer toothed ring 52 sleeved on the outer side of the movable rod 46, and the outer toothed ring 52 is movably engaged with the first inner toothed ring 51. The lifting plate 56 is equipped with a first guide rod 57 slidably matched with the upper cover 2, and the upper cover 2 is equipped with an electric cylinder 58 connected to the lifting plate 56. The end of the lifting plate 56 away from the connecting ring 55 is rotatably connected to a transmission gear 59, and the transmission gear 59 is movably engaged with the driven gear 48; The material distribution component 6 includes a second inner tooth ring 61 movably arranged inside the upper cover 2, the second inner tooth ring 61 is movably meshed with the transmission gear 59, the second inner tooth ring 61 is rotatably matched with a support ring 68 arranged on the inner wall of the upper cover 2, and a rotating disk 63 is movably arranged inside the upper cover 2 and is sleeved on the outer side of the rotating drum 3. A plurality of partitions 64 are circumferentially distributed on the inner side of the rotating disk 63, and a plurality of through holes 65 are distributed on the bottom of the rotating disk 63. A plurality of second guide rods 62 connected to the second inner tooth ring 61 are slidably arranged on the rotating disk 63, a guide ring groove 67 is provided on the inner wall of the upper cover 2, and a plurality of sliding columns 66 are slidably provided in the guide ring groove 67, and the sliding columns 66 are connected to the outer wall of the rotating disk 63.

At this time, the position of the movable rod 46 is fixed, the motor 410 drives the driving gear 49 to rotate, and the driving gear 49 drives the rotating drum 3 to rotate by meshing with the driven gear 48. Since the position of the movable rod 46 is fixed, the first bevel gear 45 drives the connecting rod 44 to rotate around the axis of the first bevel gear 45 by meshing with the second bevel gear 47, so that the connecting rod 44 can rotate on its own and rotate circumferentially around the movable rod 46, thereby realizing the rotation of the stirring paddle 43 in different directions; At the same time, the driven gear 48 drives the transmission gear 59 to rotate by meshing with the transmission gear 59 and the transmission gear 59 is meshed with the second inner gear ring 61. The transmission gear 59 drives the rotating disk 63 to rotate synchronously by rotating with the support ring 68 and sliding with the second guide rod 62 and the rotating disk 63. The rotating disk 63 drives the powder thereon to rotate synchronously. The rotating disk 63 is reciprocated and lifted in the vertical direction by sliding with the slide column 66 and the guide ring groove 67. The rising stage of the rotating disk 63 is a gradual inclined rise, and the descending stage of the rotating disk 63 is a vertical descent, so that the shaking of the rotating disk 63 during the rotation process can be achieved. A plurality of partitions 64 divide the internal space of the rotating disk 63 into a plurality of unloading areas. The rotating disk 63 drives the powder located in different unloading areas to shake by its own shaking. The powder passes through the through hole 65 and falls above the liquid material in the mixing box 1, so that the powder is fully and evenly unloaded, and the powder is prevented from being fed into a certain area inside the mixing box 1, so as to facilitate the rapid and uniform mixing of the powder and the liquid. When the switching assembly 5 is in the first state, the electric cylinder 58 extends downward and pushes the lifting plate 56 downward by connecting with the lifting plate 56 and slidingly cooperating with the first guide rod 57 and the upper cover 2. The lifting plate 56 drives the connecting ring 55 and the transmission gear 59 to move downward synchronously, releasing the meshing between the transmission gear 59 and the driven gear 48 and the transmission gear 59 and the second inner gear ring 61, so that the rotating disk 63 no longer rotates; At the same time, the connecting ring 55 drives the slide cylinder 53 downward by being rotatably connected with the slide cylinder 53, releases the engagement between the slide cylinder 53 and the guide cylinder 54, and makes the outer gear ring 52 engage with the first inner gear ring 51. The synchronous rotation between the rotating drum 3 and the movable rod 46 is realized by the engagement between the first inner gear ring 51 and the outer gear ring 52 and the sliding cooperation between the slide cylinder 53 and the movable rod 46. The motor 410 drives the driving gear 49 to rotate, and the driving gear 49 drives the rotating drum 3 to rotate synchronously by meshing with the driven gear 48. The rotating drum 3 drives the movable rod 46 to rotate synchronously by cooperating with the switching component 5 and the movable rod 46, so that the second bevel gear 47 provided on the movable rod 46 rotates synchronously with the rotating drum 3, and the position of the first bevel gear 45 can be relatively positioned.
